3.9" Banded Iron Formation Section - 2.5 Billion Years
This is a beautiful, 3.9" wide section of a 2.5 billion year old banded iron formation, collected from Fremont County, Wyoming. The specimen appears to have been lightly tumbled to give it a smooth feel and bring out the alternating orange and brown bands. These BIFs are some of the oldest rocks found in the state.
It displays beautifully on the included acrylic display stand.

Banded Iron Formations (BIFs) are among the oldest rocks on Earth, with origins dating back over 2 billion years to the Precambrian era. These formations are significant not only for their beauty but also for their historical and geological importance, as they were formed in Earth's early oceans when oxygen levels began to rise, leading to the precipitation of iron. This process helped pave the way for the more oxygen-rich atmosphere we rely on today.
